chines adapted to be quickly convertedinto a machine for sawing wood or other material Heretofore in cutting ice in large quantities ice-plows have usually been used drawn by horses, and though sometimes operated in gangs it is usually necessary for the plow to traverse the cut a plurality of times before the ice has been cut sufficiently deep to enable the block to be cleaved off with an ice space. Q

The object of this invention is to afford a machine adapted to cut one or more lines of blocks at a time and though drawn by horses or other suitable motive power is provided with an independent motor or othersuitable mechanism to drive either one or a gang of saws, as preferred.-

- It-is also an object of this invention to afford a construction adapted to' be quickly converted, principally by change of saws,

.from an ice to a wood cutting machine, thus afiprding a sawing-machine adaptable for use as a general sawing-machine;

The invention embraces many novel features and consists in the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a side elevation showing the machine adjusted for outaffording means for attaching draft-animals. Said runners or skids are connected at the rear of the roll a by means of connected pipes a which may serve as radiators forcooling 6.0 the motor should a water-cooling explosiveengine be used. Supported on said pipe is 'a rigid platform or deck B, on which is secured an explosive-engine of any desired "hOI'Sew power or' construction, and the cylinder thereof may be cooled by water,-if preferred. For this purpose a water-tank c is 'shownsup-' ported near the front upon oneside of the platform, while the gasolene tank or reservoir 'c' is supported on the opposite side of the platform, thus distributing the weight over the platform as uniformly as possible. J ournaled on said frame and runners transversely of the same near the rear end thereof is a shaft.

D, the ends of which have hearings in the 7 boxesd at each side themachine and upon which in alinement with the sprocket-wheel c of the engine is a sprocket-wheel d, which is rigidly secured upon an elongated sleevehub 11 of the sprocket-wheel (1 from whencethe saws are driven. Collars df are rigidly secured .on each end of the shaft D, bearing against the inner end of theboxes d and act to hold said shaft from longitudinal movement, and rigidly secured on said shaft, at a distance apart corresponding with the width of out desired are rearwardly-directed parallel arms D, D and D each of which is slotted longitudinally at the outer end to receive'a saw. Said arms are rigidly connected by rods d and d, which may be securedin any suitable manner upon the arms D and D and D Journaled on the outer end of is an arbor provided with collars e at each end ofthe same .to hold the same from longitudinal movement, and rigidly secured thereting ice, with the saws down. Fig. 2 is a top plan view of the same. ,Fig'. 3 is a transverse section of the frame and saw-arms. Fig; i is an enlarged detail illustrating the means for on is a sprocket-wheel e in alinement with the sprocket-wheel d and receiving the n 4 sprocket-chain e therefrom. Upon said ar-' bor E, between the bearings afforded by the securing the saws upon the shaft or arbor.

' Fig. 5 is an enlarged fragmentary detail illustrating the operation of the gage or guideshoe. Fig. 6 is a side elevation of the ma chine, showing the same adjusted for cutting 'ood. c

As shown in said drawings, A A indicate unners or skids connected, as shown at the front, by means of a roller a, to which is secured a pole or tongue 0/ in the usual manner,

forked ends of the arms D- and D and D are saws E, E and E which, as shown, are

rigidly bolted to collars e and e, keyed on the arbor E, and which fit between the bearings at the end of each arm, as shown in Figs. 2- and 4. Said saws when used for cutting ice 'either singly or in gangs, as shown in Figs. 1, a 2, and 3, are gummed, as is usual for a rip- 1 io saw-'that is to say, are gummed' to afford considerable lead for each toothand said toothed segment f secured on the platform, and whereby the operator is able to rotate the shaft D adjusting the saws either for cutting below the sled or with the arms directed vertically to enable the'machine to be used for wood-cutting.

A guide G is provided on each runner to hold the machine to tlie cut when sawing ice. For this purpose a plate or blade, of steel or "other suitable material, is provided with a plurality of transverse slots and engaged upon pins or screw-bolts g, extending through the slots and scented in the side of the run-- ner. Bellcrank levers g are pivoted'on the side of the runner above and at each end of the guides G, and corresponding arms of the same are connected withthe upper edges of said plates. The upwardly-directed arms thereof are pivotally connected with rods-g one for each plate and the ends. Preferably the rear end of each rod is engaged by a lever g, whereby said rod y" is adapted to be shifted forwardly in elevating the plate or rearardly in lowering the plate into a cut formerly made in the ice. Said saws are so arranged thatthe end saws on the arbor are at a distance from the adjacent guide-plate G equal to the distance between the .sawsE and E or, in other words, the desired width of the ice block.

When it is not desired to use the machine for sawing ice, it may be converted into a machine foreither ripping; or cross-cutting wood. This is done by removin the cap 6 from the boxes for the arbor an removin all the saws from the arbor and substituting a single crosscut saw, vas shown by E, or a rip-saw, dependent upon the work to be done. The lever l1 enables the arms to be thrown to a vertical position, as indicated in Fig. 6, and when so elevated spuds (Z preferably pivoted upon the platform, engage at their rear ends in eyes in eacharm, affording a brace therefor, and tension-rods (1", preferably each provided with a turnbuckle d extend from an eye on each arm D and D and forwardly and engage upon the platform, thus when the arms are elevated for wood-sawing rigidly bracing the same and preventing vibration when the saw is in operation. I

Any suitable sawing frame or platform may be constructed, as indicated in Fig. 6, and the same may belconstructed' of wood or metal, as preferred,.and the form of the same may of course vary, dependent upon the use to which the saw is to be put, either forzcrosscutting or ripping material. Usually, however, a simple frame .is constructed ofyany material and sufliciently braced to support the material and may either be furnished with ice-field having been selected thejmachine is positioned at one corner of the field and the saws lowered to operative position and driven by the motor. The sled is then drawnin a straight line to the opposite. end

of the field. The machine is then turned about, the guide G is inserted in the last out made, and the course is retracted, thus providing as many parallel cuts longitudinally of the field as desired, the horses all the time walking upon solid-or uncut ice. The saws are adjusted to leave a sufficient thickness of ice at the bottom to support the team and machine in cross-cutting. Having laid off the field longitudinally, the machine is then started at one end ofthe field and in the same manner is drawn transversely of the previous cut, and, as shown, as the first-line cuts have been made transversely the ice may be blocked out and removed as fast as the cutting proceeds, In this way any number of saws may be used on a single machine and operate at onetime, and of course the saws being driven by the motorthe rate of out can be adjusted to require very slight draft on the team. When used for woodsawing, either cross-cutting or ripping, a saw of'the proper kind'is secured in lace upon thearbor, and the saws are eevated, as

shown in Fig. '6, and rigidly braced in position by means of the spuds d and brace-rods d and when thus firmly secured may be used as any other wood sawing or riping machine either for shop purposes or, desired, in the woodyard. Obviously inasmuch as I have shown'b ut one'construction embodying my invention Ido not purpose limiting this application for patent otherwise than necessitated by the prior art, as many details of construction and operation may be varied, a'nd,.if preferred, instead of supporting the machine .on runners wheels of trucks may be used, and any variety or type of motors, saws, or connection between the motors and saws may be employed without departing from'the principles of my invention.
